Reference documentation and code samples for the Google Cloud Spanner Instance Administration v1 API class FreeInstanceMetadata.
Free instance specific metadata that is kept even after an instance has been
upgraded for tracking purposes.
public FreeInstanceMetadata.Types.ExpireBehavior ExpireBehavior { get; set; }
Specifies the expiration behavior of a free instance. The default of
ExpireBehavior is REMOVE_AFTER_GRACE_PERIOD. This can be modified during
or after creation, and before expiration.
Output only. Timestamp after which the instance will either be upgraded or
